Well, I think mine are going flat. I got underneath and it looks like I have PR-4b made by EMCO which are suppose to be made for up to 3500lb axles. I got info from Etrailer.com and they said the PR-4s from Redline will fit with a higher capacity (up to a 4800lb axle). Anyone else that has a 292BHDS, if you would not mind looking underneath at the spring for the tab I took a pic of to see if they have the same spring. I would appreciate it. I am seriously thinking about changing them out. I am curious if the weight in the trailer with people, water ect is stretching these things out while camping? Here are a couple pics:

I had this problem on mine as well. Verified by the dealer that they where indeed flat and he wouldn't let me pull it without fixing it. It took pics and CAT scale verification and Coachmen stepped up and paid for it. IF I hadn't provided the scale numbers they where going to reject the claim as they told my dealer I was probably overweight.

Replaced my springs. I am currently communicating with Lippert to see if they will help with cost. Shipped them back to factory for testing. They claim I was overload but had a weight ticket stating otherwise (7450 lbs) with gear and water.

Less than $400 installed at dealership including cost of springs. I also went ahead and went with the 2000lb springs. I now have approx 3-4 inches above the tires to bottom of trailer. Dealership is less than a mile away so I have not be able to tell a towing difference yet but mechanic said it should be a lot less sway if I had any. I also replaced the china bomb tires with khumos d rated and that made a huge difference.

I had the same issue with my springs. It was so bad the tires were striking the floor of the trailer and was rubbing a hole in the floor. Lucky I caught it and had a experience truck suspension shop replace them. I'm surprised the tires didn't blow as a result, I was hearing others were having similar problems. I had it done in Canada for under $600 taxes in.
